Beam quality: The energy spread of the beam was determined to be about 1%.Target: A self-supporting 600 µg/cm2 foil of 9Be was used as a target.Data obtained: author graph (digitized with GSYS 2.4)Angular distributions of the 9Be(11B,X) reactions were measured at the energy Elab = 45 MeV using the 11B ion beam from the Warsaw University cyclotron U-200P.
